SIMediationSession

The SIMediationSession public interface defines the methods for querying and interacting with the service integration bus. As well as defining the methods for working with the service integration bus, this interface also includes methods that provide information about where the mediation is invoked from, and the criteria that are applied before the message is mediated.

Both selector and discriminator control which messages are sent to the mediation, through a rule specified in a text string. The rule specified by the selector examines the header and properties of the message, whereas the discriminator examines the topic of the message. If a message contains both selector and discriminator, it must match both rules for the message to be mediated. If either the selector or the discriminator rule does not match, the message is not mediated.

The API has these methods:

• getBusName returns the name of the bus upon which the mediation is associated.
• getDestinationName returns the name of the destination with which the mediation is associated.
• getDiscriminator returns the discriminator defined in the mediation definition.
• getMediationName returns the name of the mediation being used executed.
• getMessageSelector returns the message selector defined in the mediation definition.
• getMessagingEngineName returns the name of the messaging engine from which the mediation was invoked
• getSIDestinationConfiguration returns the SIDestinationConfiguration object associated with the destination, specified by destinationName or destinationAddress.
• receive receives an SIMessage from the service integration bus. There are four variants.
• resetIdentity changes the identity of the given message to the current run-as identity.
• send sends a copy of an SIMessage to the service integration bus, in addition to the message returned by the message interface.
